He can stratify the population in to three such as science graduate, social science graduate, commerce graduate. If proportional representation is used in an election, a political party that wins 10% of the vote, will win 10% of the seats in parliament and a party that wins 20% of the vote, will win 20% of the seats..

Representation by population is a political system in which seats in a legislature are allocated on the basis of The adolescents, youths in Telungana can be treated as examples for infinite population, though they can be counted but in complex procedure. If the last page were reached before completing the proposed sample size, the count would continue from the first page of the directory until it complete its intended sample size.Differentiate between sampling frame and sampling unit with example.Describe the advantage and limitations of stratified random samplingIn this homework assignment students will be asked to understand population, sample and various sampling techniques Meaning of Representation, ...
